Question 1

What is a 2FA Generator?

Accepted Answer

A 2FA Generator creates Time-based One-Time Password (TOTP) codes used for two-factor authentication. It works the same as apps like Google Authenticator or Authy, generating a new 6-digit code every 30 seconds from your secret key.

Question 2

Is this 2FA Generator safe to use?

Accepted Answer

Yes. This generator runs 100% in your browser. Your secret key is never sent to any server. All TOTP code generation happens client-side using the standard RFC 6238 algorithm.

Question 3

Which services does this TOTP generator work with?

Accepted Answer

It works with any service that supports TOTP-based 2FA, including Google, GitHub, AWS, Microsoft, Discord, Binance, Coinbase, Salesforce, Okta, and thousands more. It supports SHA-1, SHA-256, and SHA-512 algorithms with 6, 7, or 8 digit codes.

Question 4

How do I use this 2FA code generator?

Accepted Answer

Simply paste your Base32 secret key into the input field and click Generate. The tool will instantly create your TOTP code with a countdown timer showing when the code expires and a new one is generated.
